The temple was surrounded with paddy field hence the name Thiru Nelvoyil.
At present the place is well known as Sivapuri.

Sthala Purana says Thiru Gyana Sambandhar who is great devotee of Lord
Siva, was blessed by Lord. When he was 3 years old, his father left
him on the steps of pushkarani to have bath. The child was hungry and cried for
milk. Goddess Parvathy gave him milk. When his father came he saw
milk in the lips of child, asked the child who gave him milk. He pointed the
hand towards temple and sang his first Hymn in praise of Lord. His
father Sivapadhar felt happy to know this.

Thiru Gyana Sambandhar along with Nayanmars and relatives was
traveling to Achalpuram
Siva Temple
for his marriage ceremony. They members in marriage party were hungry when
they reached this place Sivapuri. Lord Siva in guise of the temple
priest fed the party with delicious food. So the lord was praised by them as Uchinadhar
/ Madhyaneswarar.
